A plane doing 400 mph can zoom at least 5300 ft. What's guns range? 500 yrds? 1000 yrds? Well, if you wanna stay outta guns range, you need to be much faster and zoom anywhere from 1500 to 3000 ft higher.
This means that the 'other' plane has to be slow enough to not zoom more than 2300-3800 ft. It works out that the plane needs to be slower than 260-340 mph. In other words, at 340 mph, the Typhoon would have zoomed to within 500 yrds of you, and at 260 mph, he would have still been within 1000 yrds. If he climbed *at all* during his turn, even at a shallow 5 degree pitch angle (his climb rate would have been around 3k/min), his e-state was probably not as low as you thought. He was probably not 'losing' much energy, but keeping it rather constant, trading speed for altitude in a chandelle type maneuver. This is where film can be 'extremely' useful, to really analyze what the other guy was actually doing, compared to what you thought he was doing.
